Description

Technical Field

[0001] This application relates to the field of tea processing equipment technology, and in particular to a tea kneading machine with adjustable pressure. Background Technology

[0002] After the fresh leaves are picked, tea leaves need to undergo multiple processing steps to become tea. First, the fresh leaves are graded. After grading, the fresh leaves of the same grade are consistent in size and tenderness. Then, the fresh leaves are withered. After withering, the tea leaves need to be rolled. Nowadays, rolling machines are generally used to roll the tea leaves.

[0003] However, existing tea rolling machines often use fixed pressure during the rolling process, making it difficult to flexibly adjust the pressure according to the different types of tea and the processing requirements of different rolling stages. This results in inconsistent tea quality. Furthermore, the rolled tea needs to be screened, but traditional tea screening methods rely heavily on manual screening, which is inefficient and increases the labor intensity of manual workers, thereby reducing the utilization efficiency of the rolling machine. Utility Model Content

[0004] In view of the above problems, this application provides a tea rolling machine with adjustable pressure to solve the problem that the pressure of existing tea rolling machines is often fixed during the rolling process, making it difficult to flexibly adjust the pressure according to the process requirements of different types of tea and different rolling stages, resulting in inconsistent tea quality. In addition, the rolled tea needs to be screened, but traditional tea screening methods mostly rely on manual screening, which is inefficient and increases the labor intensity of manual workers.

[0005] This application provides a pressure-adjustable tea rolling machine. The pressure-adjustable tea rolling machine includes a worktable, inside which a rolling disc is fixedly installed. A limit frame is fixedly connected to one side surface of the worktable, and a controller is fixedly installed on the back of the limit frame. A rolling adjustment mechanism is provided above the surface of the rolling disc, and a vibration screening mechanism is provided below the bottom of the rolling disc. A collection frame is provided below the vibration screening mechanism.

[0006] In some embodiments, a drive motor is fixedly mounted on the top surface of the limiting frame, and a threaded rod is fixedly connected to the output end of the drive motor, with a smooth rod provided on one side of the threaded rod.

[0007] In some embodiments, a threaded slider is movably mounted on the surface of the threaded rod, the interior of the threaded slider is slidably connected to the surface of the smooth rod, and a connecting plate is provided on one side surface of the threaded slider.

[0008] In some embodiments, the kneading adjustment mechanism includes a drive box fixedly installed on the upper surface of a connecting plate, a second drive motor fixedly installed inside the drive box, and a drive gear fixedly installed at the output end of the second drive motor.

[0009] In some embodiments, a driven gear is meshed with the outer surface of the driving gear, a rotating rod is fixedly connected to the inner wall surface of the driven gear, a pressure plate is fixedly installed at one end of the rotating rod, a pressure sensor is fixedly connected to the bottom of the pressure plate, and a kneading wheel is fixedly installed at the bottom of the pressure sensor.

[0010] In some embodiments, the vibrating screening mechanism includes a screening cylinder located below the bottom of the kneading disc, a fixing frame is fixedly installed on the outer surface of the screening cylinder, and a screening plate is fixedly installed at the bottom of the screening cylinder, with a vibrating plate fixedly connected to the outer wall surface of the fixing frame.

[0011] In some embodiments, a vibrating rod is movably connected inside the vibrating plate, a connecting plate two is fixedly installed at the bottom end of the vibrating rod, and a spring is sleeved on the surface of the vibrating rod. A resonant column is fixedly connected inside the connecting plate two, and a vibrating motor is fixedly installed at the bottom end of the resonant column.

[0012] The above scheme utilizes a drive motor installed inside the drive box. This motor drives the active gear, which meshes with the driven gear, causing the rotating rod to rotate. The rotating rod then drives the pressure plate, which in turn drives the kneading wheel to perform the kneading process. During kneading, a pressure sensor monitors the pressure applied to the tea leaves in real time. The pressure sensor transmits signals to the controller to adjust the kneading pressure, thus improving the machine's kneading efficiency. A screening cylinder collects the kneaded tea leaves, which fall onto the surface of a screening plate. A vibration motor then drives a resonant column to vibrate, which in turn drives a connecting plate. This connecting plate, in conjunction with a vibrating rod, transmits force and, through the connection of the vibrating plate, causes the fixed frame to vibrate, which in turn vibrates the screening cylinder. The high-frequency vibration of the screening plate, driven by the vibration motor, causes the tea leaves to jump and tumble on the screening plate, achieving separation and screening based on particle size. This results in higher-quality tea leaves and improves the overall quality of the final product.

[0025] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0026] First, it should be noted that the kneading machine in this application embodiment can be applied to tea processing or to other equipment, and this application does not limit it.

[0027] This application provides a tea rolling machine with adjustable pressure. Figure 1 This is a perspective view of a kneading machine in some embodiments of this application. Figure 2 This is a perspective view of the kneading adjustment mechanism in some embodiments of this application. For example... Figure 1 , Figure 2As shown, the pressure-adjustable tea kneading machine includes a worktable 1, a kneading disc 2 fixedly installed inside the worktable 1, a limit frame 3 fixedly connected to one side surface of the worktable 1, a controller 5 fixedly installed on the back of the limit frame 3, a kneading adjustment mechanism 4 provided above the surface of the kneading disc 2, and a vibration screening mechanism 6 provided below the bottom of the kneading disc 2, a collection frame 7 provided below the vibration screening mechanism 6, a drive motor 31 fixedly installed on the top surface of the limit frame 3, a threaded rod 32 fixedly connected to the output end of the drive motor 31, a smooth rod 33 provided on one side of the threaded rod 32, a threaded slider 34 movably installed on the surface of the threaded rod 32, the interior of the threaded slider 34 slidingly connected to the surface of the smooth rod 33, and a connecting plate 35 provided on one side surface of the threaded slider 34.

[0028] In the technical solution of this application embodiment, the machine is controlled by the controller 5. The drive motor 31 drives the threaded rod 32 to rotate and cooperates with the smooth rod 33, so that the threaded slider 34 can move vertically on its surface, thereby driving the connecting plate 35 to rise and fall, which facilitates the adjustment of the kneading adjustment mechanism 4.

[0029] According to other embodiments of this application, such as Figure 3 As shown, the kneading adjustment mechanism 4 includes a drive box 41 fixedly installed on the upper surface of the connecting plate 35. A second drive motor 42 is fixedly installed inside the drive box 41. A drive gear 43 is fixedly installed at the output end of the second drive motor 42. A driven gear 44 is meshed with the outer surface of the drive gear 43. A rotating rod 45 is fixedly connected to the inner wall surface of the driven gear 44. A pressure plate is fixedly installed at one end of the rotating rod 45. A pressure sensor 46 is fixedly connected to the bottom of the pressure plate. A kneading wheel 47 is fixedly installed at the bottom of the pressure sensor 46.

[0030] In this embodiment, the drive motor 42 installed inside the drive box 41 is started, which drives the drive gear 43 to rotate. The drive gear 43 and the driven gear 44 are meshed, which in turn drives the rotating rod 45 to rotate. The rotating rod 45 drives the pressure plate, which in turn drives the kneading wheel 47 to perform kneading. During the kneading process, the pressure on the tea leaves is monitored in real time by a pressure sensor 46. The pressure sensor 46 and the controller 5 transmit signals to adjust the pressure, thereby improving the kneading efficiency of the machine.

[0031] According to other embodiments of this application, such as Figure 4As shown, the vibrating screening mechanism 6 includes a screening cylinder 61 located below the bottom of the kneading disc 2. A fixing frame 62 is fixedly installed on the outer surface of the screening cylinder 61, and a screening plate 63 is fixedly installed at the bottom of the screening cylinder 61. A vibrating plate 64 is fixedly connected to the outer wall surface of the fixing frame 62. A vibrating rod 65 is movably connected inside the vibrating plate 64. A connecting plate 66 is fixedly installed at the bottom end of the vibrating rod 65, and a spring is sleeved on the surface of the vibrating rod 65. A resonant column 67 is fixedly connected inside the connecting plate 66, and a vibrating motor 68 is fixedly installed at the bottom end of the resonant column 67.

[0032] In this embodiment, the screening cylinder 61 is used to collect the kneaded tea leaves and place them onto the surface of the screening plate 63. The vibration motor 68 is then activated to drive the resonance column 67 to vibrate, which in turn drives the connecting plate 66. The connecting plate 66 is then connected to the vibration rod 65. Through the transmission of force and the connection of the vibration plate 64, the fixed frame 62 is driven to vibrate, which in turn drives the screening cylinder 61 to vibrate. The high-frequency vibration generated by the vibration motor 68 drives the screening plate 63, causing the tea leaves to jump and roll on the screening plate 63, thereby achieving separation and screening according to particle size.

[0033] The working principle of this pressure-adjustable tea rolling machine will be explained in detail below.

[0034] like Figure 1 As shown in Figure 4, firstly, the machine is controlled by the controller 5. The drive motor 31 drives the threaded rod 32 to rotate, which in turn engages with the smooth rod 33, allowing the threaded slider 34 to move vertically on its surface. This, in turn, causes the connecting plate 35 to rise and fall, facilitating the adjustment of the kneading mechanism 4. Simultaneously, the drive motor 42, installed inside the drive box 41, is activated, driving the drive gear 43 to rotate. The drive gear 43 and driven gear 44 are meshed, further driving the rotating rod 45 to rotate. The rotating rod 45 then drives the pressure plate, which in turn drives the kneading wheel 47 to perform the kneading operation. During the kneading process, a pressure sensor 46 monitors the pressure applied to the tea leaves in real time. The pressure sensor 46 and the controller 5 transmit signals to adjust the pressure and improve the kneading efficiency. Next, the kneaded tea leaves are collected by the screening cylinder 61 and fall onto the surface of the screening plate 63. Then, the vibration motor 68 is started to drive the resonance column 67 to vibrate, which in turn drives the connecting plate 66. The connecting plate 66 then works with the vibration rod 65. Through the transmission of force and the connection of the vibration plate 64, the fixed frame 62 is driven to vibrate, which in turn drives the screening cylinder 61 to vibrate. The high-frequency vibration generated by the vibration motor 68 drives the screening plate 63 to make the tea leaves jump and roll on the screening plate 63, thereby achieving separation and screening according to particle size. The tea leaves are then collected by the collection frame 7.
